Reddit discussion weighs MCP vs. APIs for AI agent tool integration

A discussion on Reddit's r/MachineLearning subreddit explores the efficacy of the Model Context Protocol (MCP) compared to traditional APIs for AI agent tool discovery and injection. The original poster, an AI tooling developer, questions whether the standardization offered by MCP outweighs the simplicity of directly pointing agents at REST APIs or internal server methods. The community is asked for best practices and opinions on the value of MCP. AI
